First, the cover of the Figure 3 is a similar view, on an enlarged scale, bowl, which is not shown, is removed to expose showing the lower end of one leg as it appears the disks, as appears in Figure 1. With the latch 55 ring IS in the raised full line position, the tool is now grasped by the handle I! to thread or insert the legs [8 downwardly through the opposite notches M of the tubular shaft wings l3, in an obvious manner. Thus, the two legs pass down through all of the disks in the stack, as appears in Figure 1, until the notches 24 are in position adjacent the bottom disk I5. Thereupon the latch ring I9 is manually slid down the channel legs is to the dotted line position thereof shown in Figure 1, until the opposite notches 20 therein releasably look over the adjacent rollers 2|. This movement of the ring I!) has obviously caused the legs l8 at their lower ends to spread apart, as appears in the dotted lines in said Figure 1, to grip and tightly engage the notches 24 with the inner peripheral edge of the bottom disk l5. Thus, the tool is now locked to the stack of disks, permitting their ready removal from the bowl ill for washing and cleansing purposes. By reversing the steps just described, the disks may obviously be returned properly to the bowl.

The intention is to cover all changes and modifications which do not depart from the spirit and scope of the invention as indicated by the appended claims.

What is claimed is:

1. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of legs which converge normally slightly toward each other, said legs adapted to be passed downwardly through the stack of disks and including means to engage the lowermost disk of the stack, and a member slidably carried on the legs for spreading them apart to cause their lower ends to be positively locked with said lower disk.

2. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of legs which converge normally slightly toward each other, said legs adapted to be passed downwardly through the stack of disks and each being provided adjacent its lower end with a notch to engage the lower disk, and means on the legs for positively spreading the legs apart to cause the notches to be tightly gripped with the said lower disk.

3. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of channel-shaped legs which normally converge slightly toward each other, said legs adapted to be passed downwardly through the stack of disks and including means adjacent their lower ends to engage the lowermost disk of the stack, and a member slidably mounted in the channel legs to spread the legs apartto cause the means mentioned to positively be latched to the said lower disk.

4. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of channel-shaped legs which normally converge slightly toward each other, said legs adapted to be passed downwardly through the stack of disks and including a notch formed at the lower end of each leg to engage the lowermost disk in the stack, and a ring member slidably mounted in the channel legs for spreading the legs apart to cause the notches firmly to grip the said lower disk.

5. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of channel-shaped legs which normally converge slightly toward each .other, said legs adapted to be passed downwardly through the stack of disks and including a notch formed at the lower end of each leg to engage the lowermost disk in the stack, oppositely disposed rollers mounted one each on each channel leg, and a slide carried in the channel legs to spread them apart to grip the notches with the lower disk, said slide including means releasably to lock with the said rollers.

6. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of channel-shaped legs which normally converge slightly toward each other, said legs adapted to be. passed downwardly through the stack of disks and including a notch formed at the lower end of each leg to engage the lowermost disk in the stack, oppositely disposed rollers mounted one each on each channel leg, and a ring member slidably carried in the channel legs to spread them apart to grip the notches with the lower disk, said ring member having portions formed therein releasably to lock with the said rollers.

7. A tool for removing the stack of disks from ie bowl of a cream separator, or the like, said tool comprising a pair of spaced legs of channeled cross section adapted to be passed down through the stack of disks and including means to grip the lowermost disk of the stack, and a latching slide member movable within the channel of the legs.

8.'A tool for removing the stack of disks from the bowl of a cream separator, or the like, said tool comprising a handle carrying a pair of spaced legs of channeled cross section adapted to be passed down through the stack of disks and having associated therewith means for positively latching said legs to the lowermost disk of the stack, and an operating member slidably carried within the channel of the legs.

9. A tool for removing the stack of conical disks from the bowl of a cream separator, or the like, said tool having a pair of legs which converge normally slightly toward each other, said legs adapted to be passed downwardly through the stack of disks and each being provided adjacent its lower end with means to engage the lower disk, and a latch member slidably carried by the legs for causing them to be spread apart for firmly locking the same with said lower disk, and releasable lock means to hold the latch member in its locking position.
